Detail the interior

If you find you have no brake lights, one of the most common solutions to the problem is the brake light switch. These switches fail often. After checking your fuses it should be the next component you inspect. The switch is mounted to the pedal cluster and is replaced by working inside the car, below the dash on the driver side. Workspace is tight so you may want to remove the front seat and lie in the car to give yourself more room.

Figure 1

Locate the brake light switch mounted to the bracket in front of the brake pedal. The pedal rests against the plunger on the switch (red arrow) when you are not applying the brakes. There is an electrical connection on the switch closer to the steering wheel (yellow arrow).

The switch is held in place by two 17mm nuts that hold it in place by tightening them down, one on each side of the mounting bracket on the shaft of the switch. Loosen the rear nut first (red arrow). This will allow you to hand hold the front nut and turn the switch out from the mount.

This photo illustrates the two nuts on the switch (red arrows); put one on before installing the switch through the mounting hole. Then thread the other on once it is in place. Adjust the placement of the switch by moving the nuts back and forth until the plunger on the switch is compressed while the brake pedal is at rest. Then snug up both washers. Install the wiring connection and you are done.
